FSUSB45 — Hi-Speed USB2.0 (480Mbps) Switch with
Dedicated Charger Port Detect
Features
Description
The FSUSB45 is a bi-directional, low-power, two-port,
Hi-Speed, USB2.0 switch. Configured as a double-pole,
double-throw (DPDT) switch, it is optimized for
switching between two Hi-Speed (480Mbps) sources or
a Hi-Speed source and a Full-Speed (12Mbps) source.
Low On Capacitance: 7.0pF Typical
Low On Resistance: 3.9Ω Typical
Low Power Consumption: 1μA Maximum
-15μA Maximum ICCT over an Expanded Voltage
The FSUSB45 is compatible with the requirements of
USB2.0 and features an extremely low on capacitance
(CON) of 7.0pF. The wide bandwidth of this device
(720MHz) exceeds the bandwidth needed to pass the
third harmonic, resulting in signals with minimum edge
and phase distortion. Superior channel-to-channel
crosstalk also minimizes interference.
Range (VIN=1.8V, VCC=4.3V)
Wide -3db Bandwidth: > 720MHz
Packaged in:
-10-Lead MicroPak™ (1.6 x 2.1mm)
-10-Lead UMLP (1.4 x 1.8mm)
8kV ESD Rating, >16kV Power/GND ESD Rating
Power-Off Protection on All Ports When VCC=0V
-D+/D- Pins Tolerate up to 5.25V
The FSUSB45 contains special circuitry on the switch
I/O pins for applications where the VCC supply is
powered-off (VCC=0), which allows the device to
withstand an over-voltage condition. This device is
designed to minimize current consumption even when
the control voltage applied to the SEL pin is lower than
the supply voltage (VCC). This feature is especially
valuable to mobile applications, such as cell phones,
allowing for direct interface with the general-purpose
I/Os of the baseband processor. An additional feature is
the detection of the 1,1 state on D+/D- to signal an
interrupt (INT) to the processor when entering a
dedicated charging port mode of operation.
Applications
Cell Phone, PDA, Digital Camera, and Notebook
LCD Monitor, TV, and Set-top Box
